Self-Control

 ... is the ability to regulate and alter responses in order to avoid undesirable behaviors, increase desirable ones, and achieve long-term goals.

• A 2011 survey found that 27 % of respondents identified a lack of willpower as the primary factor keeping them from reaching their goals. 
• One study found that students who exhibited greater self-discipline had better grades, higher test scores, and were more likely to be admitted to a competitive academic program. 
• The study also found that when it came to academic success, self-control was a more important factor than IQ scores.
• A health study found that people who were rated as having high levels of self-control during childhood continued to have high levels of physical and mental health in adulthood.
• Research has found that self-control is a limited resource. In the long-term, exercising self-control tends to strengthen it. 
  

A lack of willpower is not the only factor that affects goal attainment.

• There needs to be a clear goal and the motivation to change. Having an unclear or overly general goal and insufficient motivation can lead to failure.
• You need to monitor your actions daily towards the achievement of the goal.
• You need to have willpower.

• Avoid temptation. 
• Plan ahead. If you are faced with temptation, what actions will you take to avoid giving in? 
• Practice using self-control. Think of self-control as a muscle. While hard work may exhaust the muscle in the short-term, the muscle will grow stronger over time as you continue to work it.
• Try focusing on one goal at a time. Once you turn the behaviors needed to reach a goal into habits, you will not need to devote as much effort toward maintaining them.
